Does Collei Scale Off EM? A Comprehensive Guide to Collei’s Elemental Mastery Scaling

Yes, Collei significantly benefits from Elemental Mastery (EM), especially when used as a sub-DPS focused on triggering Dendro reactions like Spread, Aggravate, Bloom, Hyperbloom, and Burgeon. While her first passive talent scales off ATK, at lower constellations, prioritizing EM is crucial to maximizing her effectiveness in reaction-based teams. This guide dives deep into how EM affects Collei, optimal builds, team compositions, and answers frequently asked questions to help you unlock her full potential.

Understanding Collei’s Kit and EM Scaling

Collei’s kit revolves around applying Dendro and facilitating reactions. Her Elemental Skill, Floral Brush, throws a Floral Ring that deals Dendro damage to enemies it hits. Her Elemental Burst, Trump-Card Kitty, summons a Cuilein-Anbar Zone that deals AoE Dendro damage.

Here’s a breakdown of how EM benefits Collei:

Reaction Damage: The damage of transformative reactions like Bloom, Hyperbloom, and Burgeon is directly scaled by the triggering character’s EM. Since Collei is often used to apply Dendro for these reactions, increasing her EM significantly boosts the damage output of these reactions.
Spread Damage: Collei can also trigger Spread in Quicken/Aggravate teams. Spread scales with EM, similar to Melt and Vaporize, further increasing her damage contribution in those teams.
Passive Talents: While her first passive talent, Floral Sidewinder, increases the Dendro DMG Bonus of characters within the Cuilein-Anbar Zone based on Collei’s ATK, the overall contribution from EM-based reactions usually outweighs the benefits of focusing solely on ATK, especially at lower constellations.

Building Collei for EM

When building Collei for EM, consider these factors:

Artifacts

Main Stats: Prioritize EM Sands, EM Goblet, and EM Circlet. If you’re struggling with Energy Recharge, an ER Sands can be a good alternative, especially if you don’t have an ER weapon.
Substats: Focus on Elemental Mastery, Energy Recharge, Crit Rate/DMG (if running Spread), and ATK%.
Artifact Sets:
- Gilded Dreams (4-piece): This set provides a significant boost to EM for the wearer and their teammates, making it an excellent choice for maximizing reaction damage.
- Deepwood Memories (4-piece): This set is crucial for Dendro teams as it reduces the Dendro resistance of enemies hit by the wearer’s Elemental Skill or Burst. This is essential for increasing the overall Dendro damage of the team. Even if another character is already using this set, it is still beneficial to equip it on Collei to maintain uptime on the resistance shred.
- Wanderer’s Troupe (2-piece) / Gilded Dreams (2-piece): A mixed set of 2-piece EM sets can be a good budget option if you don’t have a full 4-piece set with good substats.
- Emblem of Severed Fate (4-piece): If energy recharge is a major issue, this is a great choice to get Energy Recharge and increase burst damage based on energy recharge.

Weapons

Elegy for the End: This weapon is ideal for support Collei, providing a large EM boost to the entire team and further increasing their ATK.
Stringless: A solid option that directly boosts Elemental Skill and Burst damage, making it beneficial for both reaction-based and damage-focused builds.
Sacrificial Bow: This allows Collei to use her Elemental Skill twice, providing extra Dendro application and energy generation.
Favonius Warbow: Provides Energy Recharge for the entire team, helping with energy issues.
End of the Line: This weapon is obtainable through fishing, has Energy Recharge as the secondary stat, and its passive increases damage based on Elemental Skill.

Team Compositions for EM Collei

Collei excels in teams that focus on Dendro reactions. Here are a few examples:

Hyperbloom: Collei + Electro (Raiden Shogun, Fischl, Kuki Shinobu) + Hydro (Xingqiu, Yelan) + Flex (Nahida, Baizhu)
Burgeon: Collei + Pyro (Thoma, Xiangling) + Hydro (Xingqiu, Yelan) + Flex (Nahida, Baizhu)
Spread/Aggravate: Collei + Electro (Yae Miko, Fischl) + Dendro (Nahida, Dendro Traveler) + Flex (Kazuha, Sucrose)
Bloom (Nilou Bloom): Collei + Nilou + Hydro (Xingqiu, Yelan, Kokomi) + Dendro (Dendro Traveler, Yaoyao)

FAQs: Collei and Elemental Mastery

1. Is EM better than ATK for Collei?

For most players using Collei at lower constellations, EM is generally more valuable than ATK, especially in reaction-based teams. While her passive talent scales off ATK, the increase in reaction damage from EM typically outweighs the benefit of focusing solely on ATK. If you have high constellation levels on Collei then ATK becomes more valuable.

2. How much EM should Collei have?

Aim for at least 600-800 EM. The more the better, but don’t sacrifice Energy Recharge to achieve extremely high EM numbers.

3. Is Energy Recharge important for Collei?

Yes, Energy Recharge is crucial for Collei to consistently use her Elemental Burst, which is her main source of Dendro application.

4. What is Collei’s best artifact set?

Gilded Dreams is often considered her best artifact set for maximizing reaction damage. Deepwood Memories is also crucial in Dendro teams to reduce enemy Dendro resistance.

5. What is Collei’s best weapon?

Elegy for the End is generally considered her best weapon for its EM buff to the team, followed by Stringless for its Skill and Burst damage buff. Sacrificial Bow and Favonius Warbow are also viable options.

6. Is Collei good at C0?

Yes, Collei is a viable support character at C0. However, constellations like C2 and C4 can significantly enhance her abilities.

7. Is Collei C2 worth it?

Yes, Collei’s C2 is valuable as it provides additional Dendro application, increasing the frequency of Spreads or enabling more reactions overall.

8. Is Collei good with the Stringless?

Yes, Collei is good with the Stringless. It directly increases her Elemental Skill and Burst damage, making it a strong choice for her.

9. Is Collei stronger than Amber?

Collei generally has better Dendro application and utility compared to Amber, making her a more valuable choice for Dendro teams.

10. Is Dendro MC better than Collei?

Dendro MC (Traveler) can be a better Dendro applicator than Collei, especially at higher constellations. However, Collei’s lower Burst energy cost can make her more consistent in some situations. Ultimately, the best choice depends on the team composition and playstyle.

11. What teams does Collei work well in?

Collei excels in Hyperbloom, Burgeon, Spread/Aggravate, and Bloom (Nilou Bloom) teams.

12. What does Collei scale off of?

Collei’s first passive talent scales off of her ATK stat, but her Elemental Burst damage and Dendro reactions scale off of Elemental Mastery.

13. How much Elemental Mastery does Collei give?

Collei herself does not give any Elemental Mastery buffs. However, some of her best weapon choices, like Elegy for the End, increase the team’s Elemental Mastery.

14. Is EM good for Dendro Traveler?

Yes, EM is good for Dendro Traveler. EM increases the damage of their Dendro reactions.

15. What beats Dendro in Genshin Impact?

Dendro doesn’t necessarily have a direct “counter” element in the traditional sense. Instead, it is more about elemental combinations. As such, if your team is struggling with Dendro enemies, we recommend bringing an Electro DPS like Keqing or Cyno, and ideally, a strong shielder like Zhongli or a healer.

Conclusion

While Collei’s initial passive scales with ATK, for players aiming to leverage her reaction potential, especially at lower constellations, prioritizing Elemental Mastery is the way to go. This guide, combined with continuous exploration and refinement, will ensure you’re harnessing Collei’s true power on the battlefield. Understanding her kit and building her correctly will make her a valuable asset to your team.
